SUPPORT FOR BOBBINS, COPS, PIRNS, OR THE LIKE, WHEN UNWINDING THREAD,

YARN, OR THE LIKE THEREFROM.

Application filed; September 29, 1924.

To all whom it may concern:

Be it known that we, THOMAS VVILsox and ARCHIBALD WILSON, both of The Villa, Do'agh, county Antrim, Ireland, and both subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements Relating to Supports for Bobbins, Cops, Pirns, or the like, IVhen Unwinding Thread, Yarn, or the like Therefrom, of which the following is a specification.

This invention relates to supports for bobbins, cops, pirns, and the like, which turn on non-rotating spindles whilst the thread,

yarn or the like is being taken off. Heretofore it has vbeen proposed to mount the bobbin, or the like, on a carrier which is pivoted below the base of the bobbin and is counter-weighted, the bobbin being free to oscillate on the pivot and to relieve the tension of the yarn or thread while it is being wound off the bobbin.

The object of this invention is to provide a new support for bobbins comprising a 2 fixed member or bracket, a second member pivotally mounted on the fixed member and a bobbin carrier on the second member, the pivot pins being disposed so that they Wlll be at right angles to the axis of the bobbin carrier, the arrangement being such that whilst the bobbin can oscillate to suit the changing angle of the thread or yarn and relieve the tension thereof while the same is being wound off the bobbin or the like,

yet no counter-balancing extensions or weights are required.

The pivotal centres of the second member are arranged above the base of. the bobbin and preferably either above the bobbin itself or between the ends thereof, the pivotal axis, in all cases, being transverse to the axis of the bobbin carrier. In certain cases, Where horizontal bobbins are used, the same may be located on a spindle or carrier in a second member carried by a fixed bracket whose pivots have their common axis arranged transversely to the axis of the bobbin so that the second member with the bobbin thereon can accommodate itself to the changing angle of the yarn or thread as it is wound off the bobbin.

The accompanying drawings illustrate, simply by way of example, the invention 5 as applied to the support for a wooden bobbin.

Serial No. 740,645.

Fig. l is a side elevation of the bobbin and its support.

. Fig. 2 is a front elevation corresponding to Fig. 1.

Fig. 3 shows an arrangement in which the pivotal axis is above the bobbin.

' Fig. 4 shows, in elevation, the bobbin arranged horizontally, in the pivotal member 3.

. Referring to the drawings The bobbin carrier 1 is carried on a spindle 2 removably fitted on a member i which is pivotally mounted at 4 and on a fixed bracket or support 6 on the ma chine frame 10, the axis through the pivots 4 and 5 being, in the example shown at Figs. 1 and 2, above the base of the bobllgin and transverse to the axis of the bob- As will be seen at Fig. 1 the bracket (3 7 has slots 11 therein and the pivot pins 4, 5, of the member 3 are entered into said slots. Alternately the member 6 may be provided with pivots adapted to enter and move freely in slots in the member 3. The member 3 can be readily removed.

In the example shown at Fig. 3 the pivots 4; and 5 are above the top of the bobbin with their common axis transverse to the axis of the bobbin.

In the example shown at Fig. 4 the bracket 6 is suitably supported on the machine frame 10, the member 3 being vertical and the bobbin lying horizontally, the axis through the pivots 4 and 5 being transverse to the axis of the bobbin and between the ends thereof.

As the yarn or thread is wound off the bobbin, the latter is free to oscillate about the pivots 4, 5, as indicated in dotted lines, Fig. 1, and the location of the pivots above the base of the bobbin, causes the latter.

with its carrier 2, and supporting member 3, to act as a counterbalance to the pull of the yarn or thread whereby a constant tension on the yarn or thread is maintained, without the necessity for employing counter-balancing weights or levers.

It is important, for the class of bobbin shown at Figs. 1 and 2, that the angle at which the thread is drawn off should always be such as to prevent the thread rubbing and being chafed on the edge -7 of the bobbin, and also to avoid excessive drag on the thread through such contact,

and to avoid this a stop 8 is provided which limits the backward tilt of the bobbin, the l" rward tilt of the bobbin being preferaliily limited by a stop 5). The stop 8 also ensures that the bobbin spindle or carrier will lie at a convenient angle for the operator placing a bobbin thereon, or for removing a bobbin thereii'rom, when required.

In the arrangement, Fig. 4', the horizontal bobbin 7 is free to oscillate, along with the member 3, about. the pivots 5 of the bracket (3 which is shown broken oil'. it is obvious that as the yarn or thread is wound oft from end to end of the bobbin, the pivotal support can accommodate itself thereto.

It is of course to be understood thatthe constrnctioni'; herein described are illustrative embodiments of the invention and that various changes and modifications of the deails of structure within the scope of the ap pended claims are to be considered within the spirit of the present invention.

Having now full described our invention \ve declare that whatwe claim and desire to secure by Letters Patent is: i

l A bobbin or like support coni 'irising a fixed member, a second member pivotally mounted on the fixed member and a bobbin carrier on the second member, the pivotal axis of the second member being between the base and the top of the bobbin and at right angles to the axis of the bobbin carrier.

2. A bobbin or like support comprising a fixed member with slots therein, a second member with pivots thereon adapted to enter and move freely in said slot-s, a bob bin carrier on the second member, the pi otal axis of the second member being between the base and the top of the bobbin and at right angles to theaxis of the bohbin carrier.

3. A bobbin or like support comprising a fixed member with slots therein, a second member with-pivots thereon adapted to enter and move freely in said slots, the seeond member havii'ig a cross bar arranged below the pivots-and carrying a spindle for the bobbin. the axis of said spindle being" transverse to the axis of the pivots of the second member. 1

1-. A bobbin or like support comprising a U-shaped fixed member, a second U-shaped member pivotally mounted on the fixed member and a bobbin carrier on the second member, the pivotal axis of the second member being at rightangles to the axis oi the bobbin carrier.

5. A- bobbin or like support, comprising a U-shaped fixed, member, a second member in the form of a rectangular member p'ivotally mounted on said fixed member and bobbin carrier on the sec-0nd member, the pivotal axis oi the setrond member being at right angles to the axis of the bobbin carrier.

in testimony whereof we afiix our signatures.
